KCG2.5-60L1J17 is a left-hand lead bronze worm wheel in the KCG Series, with a 60:1 reduction ratio, module 2.5, one start, and a 15 mm bore. It has a face width of 22 mm, a pitch diameter of 150.34 mm, and an outside diameter of 157.5 mm. The worm wheel is made of CAC502 material, has a standard full-depth tooth profile with a 20° normal pressure angle, and is precision grade KHK W 002 grade 4. The J17 suffix indicates a hub width of 17 mm, and the part includes a keyway and set screw. Allowable torque at 30 rpm is 98.8 N·m, with a backlash of 0.13 to 0.31 mm and a weight of 1.93 kg. The product is designed for use with KSW2.5-L1J17 worms, and secondary operations may affect coating and precision. External forces are axial and require consideration during mounting.
Module 2.5, 60 Tooth, 1 Start, Left Handed Cast Iron Worm Gear with 17mm Finished Bore
A worm gear pair, or worm gear set, consists of two gears: the worm, which resembles a spiral screw, and the worm gear (aka, worm wheel).
For the pair to mesh, the worm and worm gear must have the same pressure angles, modules, and lead directions (left- or right-hand).
A worm revolves on a shaft that’s perpendicular to the worm gear and the shaft angle is typically 90°. Because the teeth gradually mesh as the worm rotates, there is low noise and low vibration.
